passzust

Passzust is a neologism used in some discussions around digital identity, access management, and software architecture. It does not refer to a formal, widely adopted standard, but rather to a concept or shorthand that various authors use to describe transferable credential state or pass-through conditions between systems or components.

The term appears to blend the English verb pass, meaning to transmit or hand over, with Zust and its root from the German Zustand, meaning state or condition. In this context, passzust is often invoked to discuss how a credential, session state, or authorization context can be carried from one service to another without duplicating or re-authenticating, and how such transfers should be governed.

Possible meanings of passzust include: (1) a state object that represents an access credential which can be transmitted between services; (2) a design approach for propagating authentication or authorization context across component boundaries; or (3) a colloquial shorthand for a pass-through or cross-domain state in event-driven or microservice architectures.

Passzust is not tied to a formal standard, and its usage varies by author. It relates to established concepts such as tokens, session management, and identity federation, as well as to broader concerns about security, revocation, privacy, and cross-domain trust. In practice, discussions about passzust often emphasize careful handling of leakage risk, lifetime management, and clear governance of who may pass state and under what conditions.
